摘要：

The role of kinks in dislocation ledge motion during precipitation of γ′ plates in an Al-Ag alloy was studied by conventional, high-resolution and in situ hot-stage TEM techniques. It is shown that kinks are necessary for motion of the dislocation interphase boundary and that kinks may be produced by orientation, thermal and intersection events. Analysis of the behavior of kinks at the interphase boundary utilizing isotropic dislocation theory is in reasonable agreement with experimental observations. © 1990.
